I've just bought a used T60 with ATI video (dmesg below), and my
experience matches that of several other people in this thread:
suspend-to-RAM/resume does *not* work for any combination I've tried
of GENERIC or GENERIC.MP, 4.9-release or 4.9-stable, whether X is
running or not, and whether suspend-to-RAM is initiated via Fn-F4
or 'zzz'.

However, with the small kernel patch suggested earlier in this thread
(details below), suspend/resume now "95% work" for me.  This message
documents what doesn't work and what does (for the archives).


Running a GENERIC or GENERIC.MP kernel, I see slightly different
failure symptoms depending on whether or not X is running:
(a) If suspending immediately after a cold boot (after logging in as
root at the console, without X ever having been started):  After
initiating a suspend the disk light flickers, then the moon light
blinks, and stays blinking forever.
(b) If suspending from an xterm with X running:  After initiating a
suspend the disk light flickers, and the moon light blinks, then
the moon light stays on (not blinking).
An both cases the machine appears to be suspended at this point, e.g.,
the fan is off.  But if I then try to resume by either pressing the
Fn key or closing-and-reopening the lid, then
* For case (a) nothing happens.
* For case (b) the moon light blinks, the disk light flickers, then
  the moon light blinks, and stays blinking forever.
In either case the machine hangs at this point -- there's no response
to any keyboard input (including CTRL/Alt/Del or CTRL/Alt/Backspace).
(Interestingly, Fn-PgUp still turns the ThinkLight on/off, so I infer
the CPU & BIOS are still running.)  I have to power-cycle to regain
control.


As suggested by Pedro la Peu  in message
 I built
a modified kernel by commenting out the "repost all ATI video" table
entry in /usr/src/sys/dev/pci/vga_pci.c:

/*
 * disable ATI video repost (hopefully will fix ACPI suspend/resume)
 * as per suggestion by  Pedro la Peu 
 * in message  http://marc.info/?l=openbsd-misc&m=131255997922341&w=1
 */
#if 0
{   /* All ATI video until further notice */
{   PCI_VENDOR_ATI, 0x,
0x, 0x },
{   0x, 0x, 0x, 0x}, 1, 0
},
#endif

With this change (using a renamed copy of either the GENERIC or
GENERIC.MP kernel config file):
(a) If suspending immediately after a cold boot (after logging in as
root at the console, without X ever having been started), the
failure symptoms are unchanged.
(b) If suspending from an xterm with X running:  suspend/resume works
fine: after initiating a suspend the disk light flickers, then
the moon light blinks, then the moon light stays on (not blinking).
At the point the machine is suspended.  If I request a resume
(either with the Fn-key or by opening the lid) the disk light
and moon light flicker, then both go out and the machine resumes.
The ethernet (em0) works fine after the resume; I haven't tried
the wifi yet.  However, the console remains dead -- no screen
image, no response to any keyboard input *except* that
CTRL/Alt/Del does do a clean shutdown.

So, with the modified kernel, suspend/resume works fine so long as
I'm running X.  For a laptop, that qualifies as a "95% solution".

My thanks to all who replied in this thread, and particularly to
Pedro la Pau for suggesting the kernel patch which got suspend/resume
working for me.

wpi(4) did come back nicely back when resume worked on my T60. However
the console never survived a resume, only X was usable.

To clarify, with vga repost disabled, everything else including wireless 
(wpi) resumes just fine. As I don't use text consoles or ethernet very 
often I suspend and resume a lot and have no issues.

I have a diff somewhere that adds a machdep.vgarepost sysctl, I should 
dig it out after tree unlock to see if it's of any interest.

I've got a Z61p with what I assume is similar hardware (haven't got mine
handy right now so can't get a dmesg) and exactly the same symptoms. The
resume would indeed be useful even with the blank text console if only
the network got back online, but alas no. If memory serves, not even the
wpi wifi survives a suspend/resume cycle.

When I have a spare moment (I'd more likely need a weekend or so) I'll
try to debug those problems, but I've never looked at power management
before so I really have no clue as to where to begin. Should be fun. :-)

For me the "repost all ati video" change in vga_pci.c broke resume with 
similar symptoms. You could do a simple test to see if this affects you 
too. In sys/dev/pci/vga_pci.c comment out the relevant lines:

// {   /* All ATI video until further notice */
// {   PCI_VENDOR_ATI, 0x,
// 0x, 0x },
// {   0x, 0x, 0x, 0x}, 1, 0
// },

Build a kernel and see if resume gets any further.

There are other resume related problems on my Stinkpad Z61M (console is 
blank after resume and bge0 can no longer get a link) but at least the 
machine and X resume enough to be useful.

When I try to resume it starts blinking. The screen backlight does not
light up, the screen stays totally dark, same behaviour with or without
X.

Does the moon icon stay lit, start blinking, go off? Does the screen backlight
light up (even if it's black). Did you try resuming from text mode (eg no X)?

It does not work in 4.9. I haven't checked -CURRENT but I don't expect
it to work on -CURRENT either. It used to work at some point but I think
it was a change to the radeon driver that broke it (I assume you have a
